The heat sink assembly includes an integral +12 VDC fan and temperature-controlled power on at +37°C. Fan speed is regulated to compensate for changes in air pressure/density under high altitude conditions. Two MDM-15 connectors and a provided pigtail cable allow the heat sink to draw power directly from a TIMTER™ transmitter, eliminating the need for a separate external power supply. Operates from 21 VDC to 34 VDC. The wiring harness connects to any 2″ x 3″ TIMTER™, regardless of MDM-15 gender, by plugging into either the male or female connector on the heat sink. An adapter plate and Bergquist QPAD II thermal pad are also included.
Thermal Considerations
The heat sink required for a particular transmitter depends heavily on the installation. Factors such as altitude, air temperature, air flow, and mass of the mounting surface all have a substantial impact on the flow of heat away from the transmitter. Quasonix offers several types of integrated and add-on heat sinks. Please contact support@quasonix.com for the power dissipation required and heat sink recommendations for your particular TIMTER™ transmitter.
Regardless of the heat sink, Quasonix strongly suggests using a thermal pad, such as Q-Pad® II from Bergquist.
